Field Detail

### CHARSET_FOR_NON_HTML_EXPORT_TO_EXCEL

    public static java.lang.String CHARSET_FOR_NON_HTML_EXPORT_TO_EXCEL

  Unicode charset to use to encode the data when exporting to Microsoft Excel in non HTML format. This charset is to make Microsoft Excel correctly display the characters for the different languages.

### REVERSED_BOM_FOR_NON_HTML_EXPORT_TO_EXCEL

    public static int REVERSED_BOM_FOR_NON_HTML_EXPORT_TO_EXCEL

  Byte-order mark (BOM) to use when exporting in Unicode with `CHARSET_FOR_NON_HTML_EXPORT_TO_EXCEL`. It's called "reversed" because it will be automatically reversed before writing it in the output stream. For example if the expected BOM in the output stream is (in hexadecimal) FFFE, its "reversed" version is FEFF

### CHARSET_FOR_HTML_EXPORT_TO_EXCEL

    public static java.lang.String CHARSET_FOR_HTML_EXPORT_TO_EXCEL

  Unicode charset to use to encode the data when exporting to Microsoft Excel in HTML format. This charset is to make Microsoft Excel correctly display the characters for the different languages.
